I have had that problem as well. I found that if you cant find the problem, open the saved listing and go to the bottom and click on post now, instead of save. Most times, if it doesnt post, there will be a red highlight from ebay at the top of the listing, or somewhere in it, telling you what the error is, and you can correct it. Try that next time. Usually its a simple or hidden error (like no return policy or something). Hope this helps, Joe
